I seem to recall something like Airspeed Oxford crashing on to the roof of a church on the corner of Stafford Road and Woodcote Road Wallington - probably a little after the war.
Treaders, I think you and I have discussed this over a beer sometime.
Croydon, considering it pioneer status, had a remarkable history of safety. The DC-2 was by far the worst there IIRC. Incidentally, it had already aborted a take-off in fog - it was the second attempt that proved fatal.
